A key measure of success for WebM is a diverse range of contributors. For example, we are already seeing a growing number of code contributions from independent developers as well as independent implementations.

We are pleased to now offer another way to contribute, through a licensing initiative that allows the community to help further support the WebM Project. Google, Matroska and the Xiph.Org Foundation make the components of WebM openly available on royalty-free terms. Today we're announcing the formation of the WebM Community Cross-License (CCL) initiative with 17 founding members. Organizations that join the CCL agree to license patents they may have that are essential to WebM technologies to other members of the CCL.

CCL members are joining this effort because they realize that the entire web ecosystem--users, developers, publishers, and device makers--benefits from a high-quality, community developed, open-source media format. We look forward to working with CCL members and the web standards community to advance WebM's role in HTML5 video.
